Our air source heat pump electricity tariff is better value for homes with ASHPs than the standard variable tariff (Next Flex). That’s because it is designed to suit the different energy consumption patterns of an ASHP, with two periods of cheaper electricity (per unit) every day.

With a time of use tariff, the price you pay for electricity changes depends on the time of day.

Imagine it’s like rush hour on the train. When everyone wants to use electricity at the same time (like evenings when people come home), it costs more. But if you use electricity at quieter times (like the middle of the night or early morning), it’s cheaper.

This encourages people to shift their energy usage to off-peak times, which helps balance the demand on the electricity grid.

While different homes have different insulation and heat loss characteristics, the following could be a good starting point.

And don’t forget to make sure your Legionella cycle falls in one of the cheap periods.
